How to use the Chess Clock
- Pick a time control like Blitz 5+3, or keep the default.
- Press Start. White’s clock begins.
- After each move, tap your own side to start your opponent’s clock.
- The first player to reach zero loses on time.
The Chess Clock adds the increment (seconds per move) after each move, just like a tournament clock. It also counts the moves for each player.
It works for any two-player game with time limits, like Go, Scrabble, Shogi or debate practice.
